As the pioneer of luxury goods appraisal in China, Youpai gathers experts from all fields in China, focusing on the guarantee of authenticity, price and satisfaction of luxury goods, and provides targeted education courses on price checking, authoritative appraisal, personal communication and luxury goods appraisal, thus becoming a one-stop online luxury goods service platform for contemporary fashion consumers. The biggest problem that affects the accuracy of online identification is whether consumers can take clear photos, because the details of taking luxury goods are completely different from those of taking portraits in peacetime and need to be focused at close range, so platform appraisers can quickly distinguish them according to experience. Because online identification can only detect some items through picture recognition, it is affected by shooting environment such as light, angle and definition. If the photos are not clear, it will affect the accuracy of the appraisal results.
